40 mm DC axial case fan

This 40 mm DC axial case fan runs on 12 V and draws 1.38 W. It includes a speed-signal lead so the motherboard or fan controller can monitor rotation. The frame measures 40 by 40 by 20 mm, making it suitable for tight chassis spots or targeted component airflow. It is sold as a single unit.

Check mounting holes and connector

Verify that your case or heatsink has 40 mm mounting holes with the standard spacing. Confirm the fan header on your board supplies 12 V and accepts a three-pin speed-signal connector. Ensure there is 20 mm depth clearance behind the mounting surface. Buyers needing higher airflow or larger frame sizes should look at other models.
